▏Product Features

The GC3900E touch screen gas chromatograph is a high-sensitivity chromatograph product developed and optimized on the bus development platform. It has a simple and clear Chinese display interface, making it very easy for beginners

Familiarize the product with clear menus, reasonable layout, real-time display of system parameters through Flash animation, and dynamic display of realistic graphics in a short period of time, so that the instrument is not monotonous

▏Test Principle

Gas chromatograph is a separation and analysis tool for multi-component mixtures, which uses inert gas as the mobile phase and employs chromatographic column separation technology. When multiple analyses are conductedMaterial entryDuring the chromatographic column, due to various factors

The distribution coefficients of components in the chromatographic column are different, and the flow velocities of each component in the chromatographic column are also different. After a certain column lengthAfterwards, the mixed componentsDon'tLeaving the chromatographic column and entering the detector, after detection

Convert into electrical signals and send them to the data processing workstation to complete the analysis of the measured substanceDetection and analysis.

▏Test application

Basic Application

drinking water

Determination of disinfection by-products in drinking water and/or source water by gas chromatography
